TOALL WHoM im Mar coNonRN:

e it known. that we, FRANZ WAGNER and Louis SEXAUER, of' New York,` county and State of New York,

have inventeda new and improved Fluid-Meter; andwe) do hereby 'declare thatthe following is afull, clear,

and exact description thereof, which will enable. thoseffskilledin the-art tomake and use the same,v reference being had to the accompanying drawing,i`orlning partei"v thisspe'citication, in which drawing- Figure l represents a horizontal section of this invention, the line :c fr, ig."2 indicating the'plane of section.

Figure 2 is a longitudinal central section of the same, taken'in the; plane indicated by the line 'lj, iig. Figure` isa transverse section ofthe same,`t he line z z, iggl, indicating the plane-ofsection, and lookin-g in the direction of the arrow oppositeto that line.` l I Figure-4 is a similar se`tion," taken-'inthe .plane indicated 'by the line 1: :v,'iig.2 '.Similar letter-S indicate vcorresponding parts. f

is lprovidedwith-,twcstopa which, as thepiston assumes a reciprocatingmotion, bytheuid actingon it, alternately'conie in c ontactwith ,spring toggle-arms, by which the .valve is'jchanged. This valve consists of a fourway cock,- wli'iclfhasi its seat in the 'end oi. the cylinder` and whichl connects bysuitableflevers with the registering This invention 'relates to a fluid-meter, the action of which depends upon avpisten, with'a pistonrod, which i apparatus. f The fluid, ou'owing to the'meter, passes through -a mud-cistern, where sand and other impurities` are deposited,va.ndithe clean-duid only comes-in conta'ct with thel workingparts of the. meten A represents a cylinder, into which is itted a piston, B.; vSaid cylinder is bolted to one'side of a standard, C, from which projects a bracket, D, that forms the bearings Vfor the fulci'um-pins, ab, of two levers, c d d. The leverc is subjected to the.action ci' a spring, e, and its-loose end forms a. cavity to receive the end of an arm, f. This arm is pivoted to the end lof .one of the arms, al', of vthe elbow-lever d d', catches between two noses, g g', which project from the edge of a. rod, h. Thisrod-is pivoted tothe end of a radius-arm, t', which is mounted 'on the axle, j, da revolving valve, EL The joint of the toggle-arms f d is situated between two stops, lc It', which are secured to-the piston-rod B in'such a positionfthat when the piston approaches the outer end Vof its stroke; lsaid toggle-arms are thrown in the position shownin fig'. Il, and when the piston approaches the inner endcf its stroke, the toggle-arms are forced back, andifthe elbow-lever d d turns in thel direction of the arrow marked near it in fig. l1. As soon as'the fulcrum of the toggle-arms has .passed the line of equilibrium, (which is shown in dotted lines iniig. 1,) the motion `of the lever d d is accelerated by the action of the spring e, and as theA endof the arm ,d strikes lthe nose', g,of the rod thel valve E is turned almost instantaneously.

If the piston returns towards the outer endof its stroke, the change of the valve vtakes place in the same i manner, by the action of the Varm d on the nose g.

In the drawing, 'the'pistomrod is' shown slotted, and the stops Ic are situated iu its slot, but it is obvious thatv said stops might be applied to the pistonrod in any othersuitable manner. .If desired, either or both stops mayY he made adjustable. I l i i l While the piston moves towards the inner end of its stroke, the piston-rod passes into a cavity, Z, in the -standard C, (see iig. 2.)

The valve E is made slightly tapering, and it is ground into its seat in the standard C. It is supported bytwo centre-points, m m', which are adjustable by screwthreads, so that, by their action, the valve can be adjusted in its seat to the required position. Said valve isconstructed with two chambers, n nf, each of which has two ports, a` o', p15', besty 'seen in g.` 4, and from the seat extend Ytwo channels, g g', one to the discharge-pipe F,

and the otherto a-channeh'r, which communicates withthe supply-pipe G. This communication, howcver,.is

not direct, but the fluid, as it passes from the supply-pipe, into the meter, enters, through-a channel, s, into :the mud-ciste'rn' H, which is in the lower part of the standard C, and thence it rises, through the channels r and q, into either of the chambers of the valve. i

In the bottom-of the mud-cistern is fitted a valve, t, which is held up toits seat by a bolt, it. This bolt passes upthrougha slot in the. cross-bar '11, and its upper end is square and catches in a corresponding cavity in a plug, I', which is ground into a seat in the .interior of the Vstandard C. Through the bolt u passes a pin, a2',-

which bears on inclined planes b2, vsecured to the cross-barand, as the bolt is turned in the proper direction,.

said pin slides up on the inclined planes, and forces thevalve t andthe plug I up into their seats. In this position, theapertures c2 di inthe plug correspond with'the channels r e, and the Huid passes freely througftr themeter, and'all the heavy impurities, vsuch as sand, contained in the` Huid, are precipitated, and retained in the mud-cistern. v v

When it is desired to clean out said mud-ciste'rn, the bolt'u is turned back, and, in turning it, the vplug I is also turned, and the channels 7* s are closed. When thc bolt has been turned to such a position that the pin a? canpass through the Aslot in the cross-bar v, the valve t can be removed, and the mud-cistern, can he cleaned,

the fiow of the uid through the meter being stopped by the plug I.

'Whenthe valve`occupies`the position shown in tig. Lthe fluid passes throughthe channel e2 and chamber fz, (see g. 2,) into the chamber n, whence it escapes through the port-p, channel q, and discharge-pipe F.

When the piston reaches the outer end of its stroke, the valve is changed, the port p being bro'ughtopposite the channel q, (see ig. l.), In this'position', the Huid passes from the supply-pipe G through the channels s r q into theehamber n', thence through the chambery"2 and channel e2, iig. 2,fto the outer end ofthe cylinoer, and the piston begins to vrecede towards the inner end of the cylinder, the fluid behind thepis'ton being driven out through thecharnber n, port o, and channel g, to the discharge-pipe F. l

By these means a fluid-meter is obtained which operates with very little pressure, and independent of the head, under which the'uid enters v'to Aor discharges from .the meter. If the pistou has fourinehes diameter, land the Huid acts on the` same with a pressure of one pound, or even less, to the square inch, all thel friction createdby' the `working parts is easily overcome,- and no uid is permitted to pass through the meter unless it is measured. i I

Our meter` canbe. placed in the groundioor of a building, and it will indicate the Water drawn from any of the faucets in the house, Whether on the rst, second, or any other loor.-v

The registering-apparatus R issituatefl in a chamber, L, on 'the top of the standard C, and its wheels are set in motion by a levez-,312, tig. 2, which vconnects with the valve E, and which acts on a pawhhz, which engages' with the ratchetwheel'z'z. For every oscillation of the valve the ratchet-wheel is propel1e d one tooth. This connection, however, may be changed in many different ways.

The lever y?, as the same enters the chamber L, is packed so.v that no Water )vill pass to the registeringapparatus.

What We claim as new, ancl'desire to secure by Letters Patent, is-

1. The oscillating-valve E,with chambers n u' and ports o olppr, in 4combination with the reciprocating piston' B, stops lc la, toggle-arms cZj, spring-lever c, and elbowlever d d', all constructed and operating substantially as and forthe purpose described. I

2. The combination of the valve t, boltt, and plug I, in the mudcistern H, substantially as and for the purpose set forth. T s Y 3. The channelss r, in combination'with the supply-pipeG, mud-cistern H,v and cylinder A, substantially as and for the purpose described. I
